In these fanfictions, a typical trope is the oc's rapid rise to power. Given their godlike nature, they can quickly gain influence in the Game of Thrones world, which then attracts the members of the harem. Another common trope is the oc's moral conflict. Their godlike powers might give them the ability to take shortcuts or make unethical decisions, but they have to balance that with their relationships in the harem. Also, the 'exotic outsider' trope can be present, where the oc is not from Westeros and their different culture or abilities make them both fascinating and a bit of an enigma to the characters in the Game of Thrones world, which in turn affects the dynamics of the harem.
